CISCO MDS FCIP Perfomance Issue
I am doing DC to DR replication using FCIP configured in MDS 9509 3.3 (5b)
I have got 144 Mbps speed at MPLS cloud link
But for the replication from DR to DC maximum bandwidth i am getting is 80Mbps
I had modified Min and Max bandwidth option to 150
I have got 2 SAN switch , One FCIP is up and second one is down still i am getting 80Mbps transfer rate, when second link is stable its sharing the traffic between 2 FCIP as 35 Mbps per Switch
Is there any setting in SAN switch that could cause the bandwidth to specific value
My fcip parameters are :-
TCP parameters
SACK is enabled
PMTU discovery is enabled, reset timeout is 3600 sec
Keep alive is 60 sec
Minimum retransmission timeout is 200 ms
Maximum number of re-transmissions is 4
Send buffer size is 0 KB
Maximum allowed bandwidth is 150000 kbps
Minimum available bandwidth is 150000 kbps
Configured round trip time is 18000 usec
Congestion window monitoring is enabled, burst size is 50 KB
